Postfix/POP3/IMAP

According to the perfect setup for debian tutorial:
In order to install Postfix with SMTP-AUTH and TLS as well as a POP3 server that also does POP3s (port 995) and an IMAP server that is also capable of IMAPs (port 993) do the following steps:

apt-get install postfix postfix-tls libsasl2 sasl2-bin libsasl2-modules ipopd-ssl uw-imapd-ssl (1 line!) this took more than 1 line...is that a problem?

<- pop3 and pop3s
<- No
<- Internet Site
<- NONE
<- server1.example.com
<- server1.example.com, localhost.example.com, localhost
<- No
when i got to this point, i only got prompts for the 1st four lines.
